From aggressive trail riding to the demands of downhill racing, the Newton ST delivers consistent cornering bite, predictable braking control and premium performance in ever-changing conditions From aggressive trail riding to the demands of downhill racing, the Newton ST delivers consistent cornering bite, predictable braking control and premium performance in ever-changing conditions The tread design features ramped center knobs to reduce rolling resistance, while tall, arch-supported side knobs provide ample braking and cornering grip Taller, meatier, and more aggressive than the Newton, the Newton ST ups the ante when front grip and loose terrain traction is a priority ULT - Lightweight casing fabric utilizing smaller thread fabric. This casing uses less rubber-making the tire more supple and faster rolling, with improved traction DRT - Rugged all-terrain compound specifically formulated to balance grip, wear and efficiency MWL - Durable mono fabric, found throughout our mountain range where cut and abrasion resistance is paramount EN - Supple casing sidewall support, utilizing 1.5-ply constructed casing increases sidewall layers by 50% to provide additional support while maintaining a supple feel EBIKE25 - has achieved a passing rating for use with E-Bikes up to 25kph and is ECE-R75 approved
